High-quality, CE marked drainage system for roofs with extensive vegetation where an extra water buffer is required. The drainage system consists of a filter geotextile, drainage core with water buffering and a vapour-permeable separating geotextile. It prevents the build-up of hydrostatic pressure against the waterproofing membrane and protects it from mechanical loads.
The perforated core and the vapor-permeable protective geotextile ensure that water vapor escapes from the XPS insulation on inverted roofs. All ND Drainage Systems from the +1 series are suitable for both warm roof and inverted roof constructions.

The rolls can be moved by just 1 person to the right spot (by hand truck or by simply rolling). The rolls are immediately ready to install.
We supply our ND Drainage Systems as rolls. This means, that all three required system layers – protection layer, drainage layer and filter layer – are unrolled at once in one motion.
Unroll, overlap and done. Since all layers are glued together, delays due to wind effects or wrongly positioned layers are nearly impossible. It can’t be quicker.
Rock & roll
The ND Drainage Systems are easy and quick to install because the filter, drainage and (sliding and) protection layer are glued together. The ND Drainage Systems are supplied as rolls, making them easy to handle and quick to unroll.
Glued, not thermally bonded
The filter, protective (and slip) layers are glued and not thermally bonded to the core of the dimpled core. This prevents damage to the mechanical and hydraulic properties of the geotextiles and the entire drainage system. It also prevents that geotextiles form being pressed between the dimples, which could jeopardize good drainage. The overlap of the filter geotextile ensures optimal filtration.
